Abstract (en)

A searcher unit realizes stable operation of the a communication system and improves system capacity by improving path detection characteristics in the baseband processing unit of a receiving apparatus using an array antenna. An array antenna radio communication apparatus comprises a searcher unit (20) operable to receive signals from at least a portion of an array antenna (21) having a plurality of antenna elements and operable to detect a path-timing of the received signals, the searcher unit comprising a correlation unit (22) operable to obtain first correlation values as correlation values of the received signals, an antenna-to-antenna correlation unit (23) operable to obtain second correlation values as correlation values of the first correlation values, and a path-timing detecting unit (27) operable to detect path-timing based on amplitude information obtained from the second correlation values, and a signal processing unit (12) operable to execute despreading of signals received from the antenna elements based on the path-timing obtained from the searcher unit.
